Remove the shell from an unboiled egg leaving the egg membrane intact. Put the egg in boiling water, and using some sort of utensil, poke and prod the thing, guiding it into a shape of somekind while it boils up and hardens -- the same sort of thing you might do with Bonsai, but much, much faster.

... and as a bonus, it's certainly stranger.

Best served with a croissant.

(some credit goes to [ldischler] for suggesting a way to get the shell off and for the idea of putting it in a box to make it a cube while boiling it. Good stuff for sure.)
